The c-concourse of the airport has traditionally been used for ground-loading only via a pair of breezeways out on to the airport's tarmac - with many Alaska Airlines flights being loaded via stairs.

"With the overall increase in air service, there has been an increased demand for gate space with a jet bridge," airport marketing manager Sean Briggs said.

Alaska has added a Boeing 737 one one of its flights each day from Boise to Seattle, in place of the traditional, smaller Bombardier aircraft it flies out of Boise.

"This jet bridge will give the airport more flexibility when dealing with larger aircraft," Briggs said. "It will primarily be used for Alaska’s mainline service, however can be utilized by other airlines, large charter flights and diverted aircraft.

The new gate will serve as C-11, at the end of one of the current breezeways.

The $900,000 project is funded by the airport's capital fund - and should be complete in October.
